Deployment Context

Where this platform fits.

Review positioning, capability notes, and deployment guidance for this xSONiC platform.

Product Positioning

XS-DC-32X400-SP-G2 is the xSONiC 32x400G SONiC spine switch for data center teams building higher-capacity leaf/spine fabrics, AI-ready backbones, and EVPN-based aggregation layers. It uses a performance-first xSONiC SKU: 32 ports of 400G, spine/core role, and a G2 Falcon-class variant.

Core Capabilities

Delivers 32x400G QSFP-DD ports for spine, super-leaf, or compact core roles.
Provides 12.8Tbps switching capacity for 400G fabric growth.
Supports VXLAN, BGP-EVPN, EVPN multihoming, MC-LAG, ECMP, and DCI patterns.
Supports RoCEv2-oriented Ethernet fabric designs and automation-led operational workflows.
Includes optional PTP timing support for financial, broadcast, telecom, smart grid, AI/ML, and other time-sensitive environments.

Technical Notes

Switching capacity: 12.8Tbps.
Packet forwarding rate: 5,600Mpps.
IPv4 and IPv6 route capacity profile: 288K IPv4 routes and 144K IPv6 routes.
MAC address entries: 128K.
Packet buffer: 48MB.
Latency profile: approximately 1500ns.
Power and cooling: 1+1 hot-swappable power supplies and 5+1 hot-swappable fan redundancy.
Physical profile: 1RU, 44 x 440 x 515mm.

Typical Deployment Scenarios

Use XS-DC-32X400-SP-G2 when 100G fabrics need a compact 400G spine layer, or when AI, HPC, cloud, and data center interconnect environments need higher backbone capacity without moving directly to 800G. It is positioned as the 400G step between 100G leaf/spine fabrics and the highest-end 800G AI fabric class.

Identity and Evidence Boundary

xSONiC SKU: XS-DC-32X400-SP-G2.
OEM reference model: CX732Q-N-V2.
Published selection baseline: 32x400G QSFP-DD, 12.8Tbps switching, 5,600Mpps forwarding, 48MB packet buffer, and the protocol and management fields listed on this page.
Quote-stage checks: confirm the exact hardware revision, airflow, power input, software image, feature scope, optics or breakout plan, support scope, availability, and acceptance tests before procurement.

Use the data center switch selection guide to compare this 400G candidate with other published platforms, then define topology and workload evidence in the AI fabric solution. If the design supports private inference, capture host-I/O, storage, and workload requirements from the xSONiC AI Inference Server evaluation page before setting fabric capacity; the links do not establish automatic cross-platform compatibility.

Applications and deployment scenarios

400G spine or core layer for high-capacity data center fabrics
AI, ML, HPC, and cloud backbones with 100G or 400G leaf interconnects
Time-sensitive distributed workloads that can benefit from optional PTP support
Data center interconnect and large-scale EVPN fabric aggregation
